What is micro generation (G98)?

Micro generation (G98) is a simple connection procedure for fully type tested installations under 16A per phase. Installations take place on a fit and notify basis.

The generation installation must meet the following criteria to qualify within the G98 guidelines:

The rated output must be under 16A per phase for connection at low voltage
Grid Interface Protection must be installed to local standards and functionally tested
The system will shut down during a power outage
An isolation switch is installed, capable of isolating all phases, and lockable in the "Off" position
A circuit diagram is displayed on-site
It is installed by an installer who has not commissioned any other generation within the local geographic region within the last 28 days or plans to install more within this region in the next 28 days

You must notify us of the generation installation within 28 days of commissioning.
